drm/i915: adjust sprite base address
Just like in:
commit c2c75131244507c93f812862fdbd4f3a37139401
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Thu Jul 5 12:17:30 2012 +0200
drm/i915: adjust framebuffer base address on gen4+
but this time, for the sprite planes. This ensures that the
sprite offset are always inside the supported hardware limits since it
becomes the offset into a page and we adjust the base address to a page
boundary.
